Sheet Metal Weight Calculator
Calculate the weight of sheet metal parts instantly based on material, length, width, thickness, and quantity. This tool is essential for fabrication, CNC machining, laser cutting, and cost estimation.
Sheet Metal
Weight Calculator
Quick Answer
👉 Basic formula:
Weight = Length × Width × Thickness × Density × Quantity
✔ Example (steel sheet):
1000 × 500 × 2 mm
→ Weight ≈ 7.85 kg
Formula (Sheet Metal Weight)
Standard Engineering Formula:
Weight (kg) = L × W × T × Density × Quantity ÷ 1,000,000
(when: dimensions in mm and density in g/cm³)
Common Material Density (Reference)
| Material | Density (g/cm³) |
|---|---|
| Aluminum 6061 | 2.70 |
| Aluminum 7075 | 2.81 |
| Carbon Steel | 7.85 |
| Stainless Steel | 7.93–8.00 |
| Titanium Grade 5 | 4.43 |
| Brass | 8.50 |
| Copper | 8.96 |
Sheet Metal Weight Reference Table
(Carbon Steel, Density = 7.85 g/cm³)
| Thickness (mm) | Weight (kg/m²) |
|---|---|
| 1 | 7.85 |
| 2 | 15.70 |
| 3 | 23.55 |
| 5 | 39.25 |
| 10 | 78.50 |
How to Use This Calculator
- Select a material (auto-fills density)
- Enter length (mm)
- Enter width (mm)
- Enter thickness (mm)
- Input quantity (pcs)
- Get instant total weight (kg)
✔ Real-time calculation
✔ Ideal for engineering and procurement
Common Engineering Uses
1. Laser Cutting & Fabrication
- Estimate raw sheet weight before cutting
2. CNC Machining Cost Estimation
- Material cost is directly related to weight
3. Material Procurement
- Calculate total sheet requirements
4. Shipping & Logistics
- Estimate transportation cost based on weight
Important Notes
- Ensure units are consistent (mm + g/cm³ recommended)
- Density varies slightly depending on alloy and condition
- For complex shapes, actual weight may differ after cutting

FAQ
How do you calculate sheet metal weight?
Use:
👉 Weight = Length × Width × Thickness × Density
What is the weight of 1 mm steel sheet?
≈ 7.85 kg/m²
Does thickness affect weight linearly?
Yes, doubling thickness doubles weight.
Can I calculate irregular shapes?
This tool is for rectangular sheets; irregular shapes require approximation.
What unit is the result in?
Typically kilograms (kg).
